countries selection as wifget or shortcode

Hey all,

We have this weird issue, we try to make sure our visitors navigate to the correct page but some ppl still manage to click the wrong continent.

eg: we are dividing our visitors into 3 categories: USA, Europe, Rest of the World and we do this with 3 big *ss buttons on an almost empty page. How simple can it be.

here is the real problem: we only sell one product but we have to have 3 duplicates because of the international warehouses and plugins we use.
Meaning Europe and ‘Rest of the World’ stay on the main website and we send them to different copies of the same product and USA clients goto a subdomain with another copy of the product.

Still USA clients manage to click Europe and vice versa meaning the orders arrive at the wrong logistic company.

Now we were thinking about a dropdown or ajax powered country list, where they have to enter or select their country and then get forwarded to the correct product.

I looked at several plugins but didn’t find anything suitable.

Any ideas on this dropdown or ajax powered country list?
